INFLATION-VALVE SUPPORT.

SPECIFICATION forming part of Letters Patent No. 654,300, dated July 24,1900.

Application filed April 2 1900.

To all whom it may concern:

Be it known that I,HENRY WILLIAM ADAMS, J r. a citizen of the UnitedStates, residing at Elgin, in the county of Kane and State of 5Illinois, have invented a certain new and useful Improvement inInflation-Valve Supports, of which the following is a full, clear, andexact description.

This invention relates to a support for receiving a valve, andespecially to such a support for attaching inflation-valves to thepneumatic tires of bicycle and other wheels and objects; and theinvention consists of a tube in which the valve is supported by itscasing,

Ty-the inner end of said tube being provided with a bushing to excludeforeign substances from entrance into said tube during the process ofapplying the tube to the article upon which it is to be used. In thecase of the apzo plication of the tube to a pneumatic tire forterference with the valve, all as I will proceed now more particularlyto set forth and finally claim.

In the accompanying drawings, illustrating my invention, in the severalfigures of which like parts are similarly designated, Figure 1 is alongitudinal section of the bushed supporting-tube. Fig. 2 is across-section illustrating the application of my invention to theinflation' tube of a wheel-tire. Fig. 3 is a lon- 3 5 gitudinal sectionof the bushed tube containing one form of inflation-valve. Fig. 4: is,a

perspective view of the bushing detached.

In the patent of John H. and Edward O.

Goss, assignors to the Scovill Manufacturing 40 Company, No.6S2,2l8,dated August 29,1899,

provision is made for supporting such a valve as that herein shown byits casing in a tube specially provided for that purpose,and which tubeis wholly independent in construction and operation from the valve andits casing,

whereby the valve as a whole may be removed bodily from thesupporting-tube at pleasure without in any manner Whatever disturbingthe connection of the supporting-tube with It has been found in theapplication of the supporting-tube to the tire by vul- Serial No.11,145. (No model.)

canization of some portion of the tire about said tube that the softrubber is liable to enter the inner end of the tube and obstruct thetube and interfere with the operation of the valve. In order to obviatethis difficulty, I

' use a supporting-tube a and'close its inner end by a bushing b, whichhas a small central air-duct c. This bushing may be a disk of metalhaving, as stated, the central opening a and the cylindrical flange d,so that the bushing may be put in position in the inner end of the tubea by forcing it therein, with or without the aid of other fastenings. Iprefer, however, to provide a circumferential inwardly-projecting bead ein'the tube a to limit the inward projection within the tube of the saidbushing. Obviously the provision of the bushing 12 is sufficient toexclude from the interior of the tube the rubber used in vulcanizing thecot to it, and thus the interior of the tube is left free to receive thevalve-casing. As will be seen by reference to Fig. 3, the tube ahas itsbottom flange embedded and vulcanized in a rubber cot f of any number ofthicknesses and of any desired construction, and this cot is afterwardcemented or otherwise applied to the air-tube g. During the process ofembedding the tube a in the cot the opening 0 in the bushing may bepreserved by closing it with a removable plug or pin, and such plug orpin may be part of the vulcanizing mold. I do not limit my invention,however, to this one way of assembling the bushed tube on an object tobe infiated.

As herein shown, the tube a is provided with a contracted neck h, whichis internally screw-threaded to engage an external screwthread t' on thevalve-casing j to support the valve-casing within said tube, and anairtight joint may be insured by the provision of a washer or packing tobe seated in a socket Z at the outer end of the tube, as in one of theforms of the invention of the Patent No. 632,218, hereinbefore referredto. However, I do not limit my invention to this last-mentionedconstruction.

The bushing 11 may be of other forms or constructions than that shown solong as it serves to protect the tube at from the undesirable entranceof foreign matter.

What I cIaim is--- a a 1. A tube for supporting an inflation-Valve inposition, said tube being made independ-V substances'from the interiorof the said tube during the process of vulcanizing the tube to anobject, substantially as described;

2. A supporting-tnbe,'for reinovably' re ceiving an inflation-Valve,made Wholly inder pendent ofthe'said inflation-valve, having its innerend provided with a bushing, and a circumferential inwardlyprojectingbead next adjacent to and limiting the inward projection of saidbushing, substantially as described. a i t v In testimony whereof I havehereunto set my hand this29th day of March, A. D. 1900.
